I just started using Ubuntu so please give me an explained answer.

I was trying to install macbuntu theme in my Ubuntu 16.10. I did the first step which was 

sudo add-apt-repository ppa:noobslab/macbuntu

This step worked fine. Next when I did,

sudo apt-get update

I got the error

W: The repository 'http://ppa.launchpad.net/docky-core/stable/ubuntu yakkety Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/docky-core/stable/ubuntu/dists/yakkety/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

These are just the last few lines which gives the error.

How do I solve this?

EDIT : This is the contents of the sources.list.d directory 

    docky-core-ubuntu-stable-yakkety.list
    docky-core-ubuntu-stable-yakkety.list.save
    noobslab-ubuntu-macbuntu-yakkety.list
    noobslab-ubuntu-macbuntu-yakkety.list.save
    webupd8team-ubuntu-java-yakkety.list
    webupd8team-ubuntu-java-yakkety.list.save
    webupd8team-ubuntu-sublime-text-3-yakkety.list
    webupd8team-ubuntu-sublime-text-3-yakkety.list.save

Output of lsb_release -a command

Follow the steps

 cd /etc/apt/sources.list.d/

 sudo -H gedit noobslab-ubuntu-macbuntu-yakkety.list

A file will open and first line will be something like this

deb http://ppa.launchpad.net/noobslab/macbuntu/ubuntu yakkety main

replace yakkety with xenial so that this line becomes 

deb http://ppa.launchpad.net/noobslab/macbuntu/ubuntu xenial main

save and exit the file and 

sudo apt-get update

Now try to install mac theme using this answer

For removing mac theme:

In case installing mac theme is not supported by your system, uninstall using:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:noobslab/macbuntu
sudo apt-get update

OR

sudo apt-add-repository remove ppa:noobslab/macbuntu
